I was up at the MakerSpace last night and tried to find the step bits. I was able to find a 1/2" one in the red toolbox, which got my hopes up as … where there’s one there is more, but unfortunately I was not able to find any of his friends. Am I just blind? I looked everywhere I could think of in the machine shop as well, but had no luck. I’d be happy to buy a set to leave at the MakerSpace, but I may need some direction as I’m sure I don’t know enough to buy the good ones. It’s also very possible I’m just overlooking something as it seems doubtful that no one has ever drilled a hole bigger than a 1/2" at the space.
Thanks for all your help!
